Statistics Final Year Topic: Weight Instability in Survey Calibration with Sparse Auxiliary Categories

This Statistics final year project uses synthetic survey samples with known auxiliary population totals to investigate a specific question in survey estimation. The analysis is designed around known generating conditions so that the behaviour of competing statistical procedures can be checked.

Why choose this project topic?

This study makes calibration weights an explicit, reproducible comparison. Working with synthetic survey samples with known auxiliary population totals lets you separate the target quantity from its estimate and explain when a statistical conclusion depends on assumptions.

How do sparse calibration categories affect weight dispersion and estimation error?

Agree the scenario ranges, sample sizes and reporting measures for calibration weights before running the study.

Proposed project objectives

01Specify the data-generating conditions for synthetic survey samples with known auxiliary population totals.
02Implement a reproducible analysis of calibration weights with documented software settings.
03Evaluate the estimates and uncertainty relevant to this question: How do sparse calibration categories affect weight dispersion and estimation error?

A suggested research approach

Compare uncalibrated and calibrated estimates under several category sparsity levels. Track convergence, extreme weights and error against population truth, with an explicitly specified trimming sensitivity analysis. Write the analysis before inspecting favourable runs, record random seeds where simulation is used, and keep generated study data distinct from observed field data.

What you will need

A written design for synthetic survey samples with known auxiliary population totals
Statistical software supporting survey estimation and reproducible scripts
A supervisor-agreed range of scenarios and computational budget

Keep your project scope clear

Matching auxiliary totals does not guarantee unbiased outcomes, and trimming alters the calibration properties.
